FRM-41076 and FRM-40735 errors

Hello, I have a Oracle 6i form that, when an application user logs in for the first time and uses the mouse to hover over a button, the form returns the error:

"FRM-41076: Error Populating Group"

After clicking "OK" to clear the error, if I hover the mouse again over the same button, this error appears next:

"FRM-40735: WHEN-MOUSE-ENTER trigger raised unhandled exception ORA-304500"

Finally, after clicking "OK" to clear this second error, any subsequent hovering over the button repeatedly continues to produce the following error:

"FRM-40735: WHEN-TIMER-EXPIRED trigger raised unhandled exception ORA-304500"

However, when logged on to the forms as the database owner, I get no errors.

This button used to work normally three months ago ... but with nothing changed, it started to give these errors out of the blue. Any ideas what this may be caused by?

I'm not a forms person but since the 'owner' doesn't get the error it points to a database permission issue.

From a quick Google on that error, it looks like the group is populated from a query.  I would log into the database as the application user and issue the same select that is used to populate the group and make sure it still has permissions.

If the app user doesn't get a permission error but gets no rows, I wonder if that might also throw that exception in Forms.

>> but with nothing changed

Sorry but this never happens.  Something changed.  ;)

Eventually the user will be able to click on the button ...

Could this also possibly point to a database that has too much data?

Never heard of a database having too much data...

I still bet permissions

I used Process Monitor to trace what ifrun60.exe was doing, and it shows that as I hover over the button, the form is attempting to access shwhnt32.dll (show hint? dll) but it can't find it. Maybe the form is trying to display a hover hint but cannot do so? Is it possible that this missing dll would cause those error messages I received?

Would you guys and gals have a copy of shwhnt32.dll that I can download? I can't find it anywhere on a web search ...

It ended up being the DLL file. Placing it in the path where the form could find it resolved the popup issues.
