Error in TOAD (ORACLE developer)

Asked By 10 points N/A Posted on -


I am an Oracle developer and I use TOAD as its sequel developer.

Whenever I try to start TOAD, an error window pops up on the screen.

The screenshot of the error is as under:


The application has encountered a problem. We are sorry for the inconvenience.
Invalid data type for "DEVMGR_SHOW_DETAILS'.
To see what data the error report contains, click here.
What were  you doing when the problem happened (optional)?

Why am I getting this error when my application is working perfectly?

Any suggestions regarding this problem are most welcome.

Looking forward to your replies
