Apps with out Class

[James Tabor]

Hi,
I noticed much of my test applications having problems finding classes.

7-zip,

Most of my test apps run fine, the rest? Anyone have ideas why Ros cannot find class?
Thanks,

Some office2000 applications also show this problem.

In most cases it's not an error. You'll recieve this message if the 
application does FindWindow to check for different instances or 
GetClassInfo to check if a class was already registered.
