anonymous 2005-04-28 15:07 viewer ~0007080	I think i had a similar problem with Action mamanger and a workaround is putting DoubleBufferd of the form to true..

ppm 2005-05-23 07:19 reporter ~0007305	drawing is bad often when Transparent=False - with Transparent=True looks good - test on D9

AHUser 2005-05-23 13:09 developer ~0007318	Does it help when you add the following line to procedure TJvCustomSpeedButton.WMPaint(var Msg: TWMPaint); ? SaveBitmap := SelectObject(MemDC, MemBitmap); try + BitBlt(MemDC, 0, 0, Width, Height, Msg.DC, 0, 0, SRCCOPY); DC := Msg.DC;

ppm 2005-05-23 23:47 reporter ~0007327	i confirm - now looks good regards
