I’ve encountered the same on other versions of OS. This probably has to do with you running on WinXP. Can you help me by running a tool SPY++ on your box?
If used wininspector myself. These tools allow you the see the internal name of the buttons on the expression window. The code in the expression maximizer depends on those names.

I think the name of the controls you mention are a little different between the different OS versions.

We might need to change the code in the ‘WindowsEnumProc’ method in program.cs to be able to move buttons on Windows XP.

Please let me know thanks!

I installed it in WinXP/VS2005/BTS2006 (right, I have to use all this … )
I’m getting the Extended Window but cannot see the OK and Cancel buttons.
Esc (aka Cancel) works fine.
But I cannot access the OK button. My feeling is to use some keyboard shortcut to get OK, but cannot find the right one. Could you, please, give me a clue, what keys I can use to access the OK button?

Thanks!
