My impression is that there have been some problems with Mathematica that are specific to Win2k systems; i.e. they didn't occur on WinNT systems. One thing that hasn't been tried in your case is running your Mathematica 4.0.2 on a think-pad with WinNT. Can you get a friend, dealer, or IBM itself to try this with you? Another thought: What is the pointing device on the ThinkPad? Could your problem have to do with a non-standard pointing device (eg. that little red joystick thing on the keypad)? Maybe there are alternative drivers out there that will interface better with Mathematica and/or Win2K. I ask this because I think there are lots of steps the operating system must carry out to decode the screen position of the pointer based on pointer motion, then decode intra-window position based on the desktop display, then pass this info to Mathematica, which has to be able to use that info to detect the "pointer entering/leaving" events that depend on pointer position, etc., prior to changing the screen display appropriately, so its easy to imagine the bug lying in the pointer driver info somewhere. -mark harder -----Original Message----- From: John Jeppson <jepp at kern.com> To: mathgroup at smc.vnet.net Subject: [mg25944] [mg25931] Bug: Mathematica 4.0 vs. Win2k on ThinkPad >Can anyone confirm (or refute) this bug I'm getting. > >Mathematica 4.0.0 (or 4.0.2) >Windows 2000 >IBM Thinkpad T20 (machine type 2647) > >Fail Case: > >1.)
