Dale, Thank you most kindly for responding. I promise not to make a habit of this; (asking you for help) but I inherited a problem that's really got me this time. Works like this: We open on a high resolution, interlaced, 4 bitplane double buffered screen, (with a window) load custom bitmaps and then display and animate bobs. A some point we need to remove a bob but when we do, the bob remaining on the screen has some "leftover" imagery remaining. The bob itself is fine (undamaged) and continues to move around properly but there remains, at the location the bob was when the other was removed, well, leftovers. This imagery flashes on and off at about 1 Hz. If we replace the bitbap the leftover is eliminated but this is not a solution. When removing the first bob, we RemIBob(), SortGList() the list and DrawGList() it twice (for the double buffering). Tried WaitBlit() followed by Delay() since we know that WaitBlit() returns when the blitter has only started it's final blit. No avail. 🙁 Are we going about this the right way? Leaving something out? Thanks bunches in advance for your time. Andre Charron 72614,1544
