Error reading Forms

[chris9672]

Some of the demos can't be opened coz the opening of some of the forms results in an "invalid property value" error.
If there were only a few mistakes they could still be corrected. Unfortunately, there are countless errors in countless TMS demos.
Here is a small example:
Project: \TMSSoftware\TMSPack\Instrumentation\Overview\Demo.dproj

Error: Form472.Position "invalid property value"
