Dialog Buttons Disappearing

[stupomer]

maybe I am having different results because I am doing some max and siz effects on the toolbar and it's not the same exact code as in the example but hard to simplify for forum posting. One thing in my actual dialog is that the buttons are painted with SendMessage of BM_SETIMAGE IMAGE_BITMAP. When I check whether a individual button is visible or not, it returns visible and hid- doesn't work on the individual button cid. However, if I hid then hid- the whole dialog hwnd, the missing buttons reappear. Could this be related to WS_CLIPCHILDREN. I realized I didn't have that on the parent dialog. Will try to add this and see whether this intermittent problem goes away. Any thoughts?
Thanks so much,
S
