Troubleshooting

When I run DrScheme, it is very slow and the disk is constantly running. Why?

You do not have enough memory to run DrScheme. If DrScheme works well for a while, and then starts paging (using the disk a lot), then your memory configuration is borderline for DrScheme. If DrScheme usually works well and has only suddenly started this bad behavior, then perhaps you have written a program that consumes an infinite amount of memory.

My Macintosh has 32 MB of memory, but I am having trouble with DrScheme. What can I do?

Make sure you quit all other applications before starting DrScheme. Also, turn off any non-essential extensions. Select About this Macintosh in the Finder's Apple menu and verify that the system itself uses less than 10 MB.

I have successfully downloaded the installer program for Windows, but the installation fails. Why?

If the installer reports a message such as ``corrupt installation detected'', the real problem may be that the installer is unable to write the DrScheme files to your hard drive, or the installer may be unable to modify the Start menu. In this case, check to make sure there is disk space available, or contact your system maintainer to make sure that you have the appropriate access privileges.

When I run DrScheme under MacOS, it sometimes freezes the whole machine. Why? Are there any potential software conflicts?

You probably do not have enough memory to run DrScheme. There are no known conflicts between DrScheme and other software.

I think I found a bug. What should I do?
