I have switched from Windows XP to Windows 7. In the dialog boxes in one program, the OK button on Windows XP used to have an "Alt+O" accelerator with it. In Windows 7, this key combination no longer presses the OK button.
Are there any settings in Windows 7 that I can change to get the XP behavior back?
The program in question is TortiseSVN. The commit dialog box in particular is where I want this. The default "enter presses OK" behavior doesn't work, because enter also enters a newline in the text box in the dialog. In XP, it was easy to type my entry and press alt+o to commit the changes. Now I have to type my entry, press tab a couple times, and press enter.
This is what I see in XP:

This is what I see in 7:

In general, alt+ works in Windows 7. But for this dialog box, for some reason, Windows 7 has chosen to turn off all the accelerators.
