I agree with Mike. I have had the same cryptic error message in an app
where it turned out that it was MS SQL Server CE objects that were no
properly closed and disposed after use.

I have ONLY had it in conjunction with SQL Server CE 3.0 and 3.5 - Not
in connection with the "real" SQL Server...

Hope this helps,
Johnny J.

Since it is a db app, can you access the database from outside of your
application on the troubled pc?  A 20 second splash screen sounds like a

long time.  Maybe the db timeout occurs and isn't handled gracefully.
Its hard to guess without knowing what your startup routines do.

As I said: Make sure all DB objects are properly closed and disposed of.

Sorry if it was unclear, Cor.
