We have just migrated our Test environment from V12.1.1 to V12.3.3. When going into ATSCON / Controlled Data Processing to 'skip' ahead the data files, we are getting 'long running scripts' and/or no returns. Other Atscon functions also give frozen screens (does not appear to be a pattern). Has anyone else experienced the same?
with the CDP page in particular, it can be very large (page wise) some browsers have trouble dealing with such large pages. It'll be a client/browser issue more than atscon.
The new 12.3 interface is more reliant on scripting to run, I've seen IE have troubles with this. Try another browser.
