We had that problem after we installed some patches to our OS (hp-ux 11.0). The we re-installed WebSpeed. Then we found out that we needed to upgrade WebSpeed beyond 9.1B06, to accomodate the OS Patches.
We upgraded to 9.1C, and that resolved the 'busy agents' problem.
However, we still have some pathing issues (.gif's) not displaying in the workshop browser window.

Move away from Progress altogether! Their software still does not work very well, or easily for that matter, with other RDBMS's.
After 8 years of working with Progress, I'm jumping ship for Oracle. I just completed installations of 8i and 9i, and it's amazing what a REAL rdbms can do.
Oh yeah - each costs about the same! I just priced them both out.
Oracle gives you a LOT more bang for your buck - and support is 10 times better.
