Bug #22545	Window messed up when maximizing

Status:	Can't repeat	Impact on me:	None
Category:	MySQL Administrator	Severity:	S3 (Non-critical)
Version:	1.2.6 rc	OS:	Windows (Windows XP Professional x64 Edition)

Description:
When I maximize or restore the MySQL Administrator window while in the Server Connections pane, the window gets messed up and an error message gets displayed. The message follows:

System Error. Code: 2.
The system cannot find the file specified.

The OK button doesn't contain any text, and I can't click it. Pressing the space bar dismisses the dialog, but leaves the Administrator window messed up. The window acts as if it doesn't have a title bar, yet, the title bar is being drawed.

Subsequently minimizing and restoring the window generates the following error message several times:

A call to an OS function failed

How to repeat:
- Start MySQL Administrator.
- Connect to a MySQL server.
- Open the Server Connections pane.
(screenshot 1)
- Maximize the window.
(screenshot 2)
- Press the space bar to dismiss the error message.
(screenshot 3)
- Note that if you switch to another window, the title bar redraws, but it isn't usable via the mouse.

After further testing, I've found this bug only occurs on dual-head systems.

My testing was wrong.

The bug manifests itself on two dual-head machines, but not on a single-head machine. However, when I disable my second monitor, the bug still occurs.

However, I did find that only double-clicking the title bar or clicking the maximize/restore button triggers the bug. Clicking the application icon or right-clicking the title bar, and clicking 'Maximize', doesn't trigger the bug.

Thank you for the report.

Could you please indicate accurate version of operation system you use?

I'm using Windows XP Professional x64 Edition. The exact version is 5.2.3790.2661 (srv03_sp1_gdr.060315-1609).

Resizing the Administrator window also triggers the bug.

This means that changing the window's size in any way other than via the application icon triggers the bug.

I've also noted a related bug in the Query Browser.

When you open the Query Browser and resize or maximize it, the resultset heading and scrollbars disappear. When you then move any splitter (for example, the one between the resultset and the schemata list), the heading and scrollbars reappear.

To reproduce:
1. Open the Query Browser.
2. Optionally, execute a SELECT query which causes the resultset to have scroll bars.
(screenshot 4)
3. Resize or maximize the window.
(screenshot 5)
4. Move a splitter
(screenshot 6)

Note that unlike the Administrator, the Query Browser doesn't display the error messages displayed by the Administrator.

I forgot to mention that the Query Browser bug only occurs on machines which exhibit the Administrator bug, and not on machines which don't exhibit that bug.

Please, try to repeat with a newer version, 1.2.4 rc, and inform about the results.

1.2.4 rc exhibits the same behaviour.

What version/SP of Windows do you use?

As I mentioned earlier, I'm using Windows XP Professional x64 Edition. The exact version is 5.2.3790.2661 (srv03_sp1_gdr.060315-1609).

Please, try to repeat with a newer version, 1.2.5 rc, and inform about the results.

Administrator and Query Browser 1.2.5 still exhibit the described behaviour.

Please, try to repeat with a newer version, 1.2.6 rc, and inform about the results.

The bug still occurs on 1.2.6 rc.

I *have* a dual monitor setup and tested this with Windows XP (32bit) both, with desktop mirroring and desktop expansion settings. I also worked with MA (and QB for that matter) on both monitors (1920x1200, both) but could not reproduce this bug, whatever I tried.

I'm not sure what to do next. Matthijs, there will be a new release of the GUI tools very soon (maybe today). Please try again with this if you still see the problem. Additionally, do you have access to another dual-head machine where you can check this? Would be good to know the behavior on a 32bit version as well.

Did you have the Server Connections panel open on the Administrator when you maximize the window? The bug doesn't appear to occur on the other panels.
Resizing also triggers the bug, but using the window menu to maximize or resize doesn't trigger it.

Unfortunately, I don't have access to 32bit dual-head machines. All dual-head machines I have access to are 64bit, and exhibit the bug.

Yes, sure, I had the threads view open, just like in your screen shot.

It might be possible this bug is not related to dual-head systems. A 64bit machine with only one screen also exhibits the bug.

A notebook running Windows 2000 does not exhibit the bug.

Neither does a Windows 2003 Server (64Bit).

Thank you for the feedback. Could you please try the latest version 5.08r.
Thanks in advance.

The bug still occurs on 1.2.8.

I'm afraid we have to postpone this report until we find a way to reproduce the described behavior.
