Installed 5.4 now Stored Procedures not working, now when looking at a stored procedure script I just get the error 'Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index'. I can load 5.2 and still see the script correctly. I did do the import settings option.
Welcome to the forum, Jim.
I also noticed issues with rendering the creation code for stored procs in 5.4, particularly for SQL Server proc code. I did submit a Support ticket to notify R&D. I'd like to suggest you opening a Support ticket also, if for anything else, to help prioritize this fix for the next release, due later this year.
We have a release coming out on October 7th (Toad Data Point 5.5) that this should be addressed in. I am double checking with the development team to make sure this fix made it into this release.
