Property profiles apparently broken in LiveCode 4.5

[David Beck]

Hello,

Something has apparently changed from 4.0.0 to 4.5 that has badly broken 
some logic in one of my stacks that use property profiles. It looks like 
the behavior of revSetCardProfile may have changed. The stack works as 
expected in 4.0.0 but is broken in 4.5.

Has anybody else experienced problems when using property profiles in 
4.5? Is this on a list of fixes?

Also, in a separate but closely related question, where can I find a the 
4.0.0 installer?

Thanks very much.
