Mouse doing the "bunny-hop"?

Does your system do this too? I`m running Win95, and in Explorer, right-clicking a file on my hard drive brings up the little menu where I can run, copy, get properties, etc. The strange thing is, clicking any other file, the menu pops right up, and if I keep the mouse moving, it smoothly moves around the screen like normal. Right-clicking on Desetup.exe, or Dep.exe (after installation ) takes about 3-4 times as long to get the menu, and the mouse starts and stops every few pixels until the menu pops up, instead of moving smoothly. Click "properties", it does the same until the properties screen appears. It`s probably nothing, but it seems kind of strange.

Dear MasterBlaster,

Could you please try to click any other EXE file?
Preferably find a big file or any other file with existing Version tab in a Properties dialog.

It seems that Windows reads a version info from EXE files (and some DLLs) before showing the popup menu.
Please write us about the result. Thank you.

Sincerely,
Alexander.

I already did. That`s what I meant by "any other file". But to make sure, I just clicked on an Internet Explorer full install file (84 Mb exe) it took 1/2 second for the menu, 1 second for Properties. No version number. I kept the mouse moving, and it made nice smooth little circles the whole time.

Tried an ATI video driver file (8 Mb exe). Again, 1/2 second to menu, 1 second for Properties, then 1/2 second for the Version tab. Nice smooth mouse again.

Back to Desetup.exe, 5 seconds for the menu, 5 seconds for Properties, 3 seconds for Version, with the mouse "stuttering" at every step. Strange stuff, eh?

Dear MasterBlaster,

Yes, it is very strange. I think this can be caused by ASPack, an executive program file packer.
Could you please right-click desetup.exe or debsetup.exe?

Thank you.

Sincerely,
Alexander

I think so too. I downloaded version 2.12 of ASPack and installed it, and right-clicking Aspack.exe took 7 seconds (!) to get the menu, another 7 for Properties, and almost 5 for the Version. It must be using all the CPU`s time to unpack the program into memory a chunk at a time, only allowing other things (like the mouse) a couple of cycles here and there. Another oddity; program files I tried compacting didn`t do the stuttering Desetup and Aspack did. Anyway, I believe the mystery has been solved. Time to get back to my regularly scheduled web-surfing. Thanks.

Dear MasterBlaster,

Thank you for your feedback.
We`ll ask ASPack author about this small problem.

Thanks,
Alexander
