Curry:<br><br>Thanks for the tips. I have 3.0a, but did not know there is a 3.0b (which I assume can be obtained from the CA website).<br><br>I am developing an application for CAR on Win98, but haven't tried to run an executable yet. Were your remarks directed to the development environment exclusively? When I close CAR, I always get a message from Win saying that the program has sinned and will be shut down - which of course I have just done. That is the only fault obviously connected with Win98. Since I do not know what is causing the problem, but the development environment seems to work, it is kind of a background worry at the moment.<br><br>Thanks again.<br>ET<br>
