This may be just the fonts on my windows box, so if it doesn't reproduce, sorry for it (but I have just the one windows box avail at current)

Enter the following sql into the query browser

select "x 'x'" UNION ALL select '"x,x",x,x';

A strange char or highlighting appears in front of the first single quote. 

As an effect the cursor is also incorrectly located. It is displayed one position in front of its real position. (painful if you need to insert or delete in the middle of the query)

How to repeat:
select "x 'x'" UNION ALL select '"x,x",x,x';

Yes, information on what the font is it will be useful.

In the first image, the grey box, before the first single quote doesnt belong there.

The dots are fine, since spaces are made visible.

Try to enter the query by hand, maybe that will do.

In my case the error happens the instant I enter the first single quote.
- It must be after an opening double quote.
- there must be additional chars between the opening dbl-quote and the single quote, and one of those must be a space.
- the space can be the directly in front of the single quote, but for on my box it can be anywhere.

changing the fonts, did not help

and it does get worse, the more space I enter.

Please, try to repeat with a newer version, 1.2.10 (from GUI Tools 5.0-r10), and inform about the results.

It does still happen in 1.2.10.

I found that it does only happens if you switch on "Show tabs and line breaks in editor" (in Tools/Options/Editors)

Switch this on before you enter/edit the query.

Verified just as described, taking into account your last comment!

This is still a problem in v 1.2.12 (as downloaded in mysql-gui-tools-5.0-r12-win32.msi). Been annoying me for ages - nice to find the work-around!
