Hello, I've found two new (to me, anyway) bugs in Windows, one mild, and one pretty nasty. To reproduce the mild bug, I: start windows with c:\> wt where wt is a 4dos alias for "win c:\telix\telix", which starts Windows up and runs the Telix comm program full screen. Now, I press Alt-ENTER to reduce Telix to a window. BUG: The cursor remains an hourglass and does not revert to the arrow. It does function normally, though, and eventually gets reset, after I do some things. This problem does not really affect me, I'm just mentioning it in case someone is gathering a list of known Windows bugs (maybe someone as MS :-) The nasty bug: I try loading in a 1024x768x256 bmp file as wallpaper, and get a UAE for Control Panel. If I try again, C Panel comes up with funny colors, and will give another UAE if I mess with the wallpaper. The background colors are also messed up now. I try once more, but this time to select a smaller bmp that does work, and PROGRAM MANAGER gives me a UAE and disappears. Now I'm basically unable to do anything, and have to reboot (Any keystrokes/mouse clicks give me the "buffer full" beep) The first time this happened, I was no longer able to boot off my hard disk, and had to reformat (sys'ing it didn't work). The second time I saw this, no damage was done to the hard disk. I think the first time, SHARE might not have been loaded in, though (It is a 200MB hard disk as one partition) which might have caused problems. Has anyone gotten a 1024x768x256 bmp to work as wallpaper? The bmp I used was converted from a gif file of the same specs, and works fine in paintbrush and WinGIF. My system setup: Gateway/Micronics 486/25 with 8MB RAM & 20MB swapfile Diamond SpeedSTAR (Tseng ET4000AX) 1MB video card using Diamond's 1024x768x256 driver Smartdrv.sys 2048 1024 NOTE: 800x600x256 bmp's work fine as wallpaper, and I have tiled other smaller bmp's to fill the whole 1024x768 area w/o any problems. Again, I don't NEED a solution, but am just looking to see if anyone else can confirm these bugs. Bryon Daly daly@omega.ecs.umass.edu

I also couldn't load a 1024x768x256 .bmp as wallpaper in enhanced mode, I could load it in standard mode though. And 800x600x256 worked fine in enhanced mode. This might have something to do with momory allocation, but I have 4 Meg + 4 Meg swap so theorectally there shouldn't be a problem. Lets hear it from someone who has successfully used 1024x768x256 .bmp as wallpaper in enhanced mode. -- Nan Zou | Bitnet : nan@ksuvm Kansas State University | Internet: nan@math.ksu.edu #include <std_disclaimer.h> | nan@phobos.cis.ksu.edu

I have had no trouble loading a 1024x768x256 bitmap. I have also used 1280x1024x256 bitmaps in 386 Enhanced mode. I have an HP Vectra RS/25C with 8M RAM and an IGC-20 graphics controller with 2M VRAM and 1M DRAM.

Looking for someone who's successuflly loaded 1024x768x256 bmps in enhanced? No problem. I use Screen Peace to select 1 of about 50 said sized bitmaps, and have never had a problem. System is: HP Vectra RS25C with 310mb, 8mb, QEMM 5.1, LanManager 1.x, smartdrv 2048 1024, etc. Oh yes- HP IGC-10 video card, which uses TI's 34010 chip and a DGIS win/3 driver for 1024x768x256. I have never had a problem, no matter what my config.sys or autoexec.bat has loaded. ie, a minimal, non-QEMM, non-LanMgr setup still allows this. The only problem has been with the disc space used for these things; I had to install a 2nd 103mb drive just for images! Douginoz "Dorothy! Dorothy! Wake up, Dorothy!"
