(win 7, VS2012 trial) I have a calculator I've been playing with for about 2 decades. Recently, I wanted to add a little window to track calculations, and I am finding that when I have the window displayed, something happens to the main calculator
window: I lose the decimal point bitmap. This tiny (12 x 12) bitmap is consistently damaged somehow, and ONLY when the extra window is showing. when I close this window, the DP is still gone. My program creates about 10 small bitmaps and I don't think I am
forgetting to close down unused DCs. Any ideas?
