I use Windows 7 with default font size set to Medium (125%). Consequently the StrokeIt window becomes too small to show all info. Text and buttons get clipped.
What would help is to make the window resizable. That's the quick fix. The neat way would be to take default font size settings into consideration.
Off topic: I believe StrokeIt and sliced bread are competing. It is a great productivity tool and probably well underestimated because of its relative obscurity. There should be campaigning for this too, seriously! Even on my smartphone I yearn for those gestures.
Suggestion: design an ad banner or button to be placed on websites (I will place it on mine) to spread the word. I'll be looking into that myself the next few weeks if I can find the time.
