Description:
I need to execute certain set of queries for a lot of primary keys. I use "Replace All" to update these primary keys. I do not close "Find and replace" panel each time. First replacements(around 15) are ok, but then each second replace throws the following exception, though replacement is done as well:

09:01:57 [ERR][      Workbench]: Der Index lag außerhalb des Bereichs. Er muss nicht negativ und kleiner als die Auflistung sein.
Parametername: index
Exception = System.ArgumentOutOfRangeException
Message = Der Index lag außerhalb des Bereichs. Er muss nicht negativ und kleiner als die Auflistung sein.
Parametername: index
FullText = System.ArgumentOutOfRangeException: Der Index lag außerhalb des Bereichs. Er muss nicht negativ und kleiner als die Auflistung sein.
Parametername: index
   bei System.Collections.ArrayList.get_Item(Int32 index)
   bei System.Windows.Forms.ToolStripItemCollection.get_Item(Int32 index)
   bei MySQL.Utilities.FindPanel.AddRecentSearchItem()
   bei MySQL.Utilities.FindPanel.button_Click(Object sender, EventArgs e)
   bei System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
   bei System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
   bei System.Windows.Forms.Control.WndProc(Message& m)
   bei System.Windows.Forms.ButtonBase.WndProc(Message& m)
   bei System.Windows.Forms.Button.WndProc(Message& m)
   bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

How to repeat:
Create some query.
Open Find and Replace Window.
Replace anything couple of times and execute query.
After around 15 replacements this bug starts to occur.

Please try version 6.3.4. Thanks.

I have a very similar issue. Every now and then, after a long time using workbench, using Find throws an error. After the error Find no longer works and I need to restart.

I'm using workbench 6.3.5 build 201 CE (64 bits).

I couldn't repeat with version 6.3.7.
