Hi,I've been using Ground2k4 5.33 for months. I keep getting a VB error while using this program : error code 480, 'Unable to create image in Autoredraw mode' (my translation of the French error message).The problem is easily reproducible, it occurs after creation of a new (blank) project, using a big .bmp image as background (usually 16000x16000 x 256 colors). When sliding up/down or left/right, the error happens, then back to desktop. The same occurs when zooming out several times. I've tried with various color depths (24 bits) or sizes...It is a very annoying bug for I have to save my work every minute or so, before attempting any move around the workspace... or else everything is lost. :/I guess it is a VB-related problem ('mode Autoredraw') and/or a video/memory management issue... My computer is stable, I use Win 2k, it has plenty of RAM... Help, any idea, anyone experienced the same ? :((I'll try to find how to join C. Fumey)Thanks in advance,HotShot

Hi HotShot.Ground2K4 is unstable when using bitmaps over 8000x8000.A work-around is to limit your desktop color setting to 16-bit depth. That seems to solve the problem for WindowsXP, and should work for Win2K.Dick

Dear Rhumbaflappy,as usual your help is unvaluable. It's weird but it works.I think I can live with 16-bit depth...Thanks ! :)
