I downloaded DXTbmp and it works fine except after I use it and close it out and then go back later to reopen it the program won't open. I go through the install process again with the file that I downloaded and it works fine until I close it and try to reopen it again??? Sometimes it will reopen if I try it right after I close it but if I wait a couple of hours or till the next day it won't open, what gives ?? I'm running FS9 on WinXP..
I've been using DXTBmp since before it was on general release. I never had a problem with it. How are you running the program? I suggest creating a shortcut to DXTBmp.exe & pasting it to your desktop.
PS. I've never used it on WinXP (never used WinXP) but I can't imagine that causing a problem.
