Thank you. The menu works perfectly now. But the more I play with the signals/slots, the more I tend to suspect it's completely buggy.

I take proven functions (like ShowAbout) on the very first window which should work, I build the project, click any buttons  - nothing works. I close the window, rebuild the project, everything works. Close the window, rebuild the project, some buttons work, some don't. Rebuild it again - they may work again 2 out of 3 times. Really strange. I thought I was doing something wrong, but this behavior certainly tells me it's not me. Do you get the same problems with working/non-working controls?
