#140 diashapes fails to run on macOS Catalina

[Alan L]

New install of diashapes on MacOS Catalina 10.15.7. mono installed prior to installation, tested and verified as running.

diashapes not running. Does not appear when starting from icon and running from XQuartz via mono produces crash report. From the outset, looks like 32 bit problem. Is this so?

Crash reports attached.
