- That's nice, but I've never used a Compaq PC, nor anything but
- whatever Microsoft mouse driver comes with whatever version of
- Windows I've ever used, and this IDE crash has always happened
- for me at some point on all machines I have ever run Borland
- C++ 4.x on. It certainly seems like an IDE bug to me. I just
- hope when I get 5.0, it stops happening.
-
- I first noticed the problem using 4.0 on Windows 3.1. It
- continues to happen, on occasion, with 4.52 on a stock Windows
- 95 installation.
