There appears to be a problem with HyperCard 2.x and Altsys Corp's "More Disk Space" INIT. This INIT performs resource compression using Apple's built-in resource compressor.
If HyperCard has at any time been compressed by this utility, it will not allow you to display large cards, regardless of the amount of memory allocated to the application. The cards will always appear smaller with the scroll window displayed.
The fix is to re-install HyperCard from the original disks. Decompressing the application does not correct the problem.
