Here's a different issue, ISC 6.1 running on Win2K3, TSM server 6.1.2, browser running on WinXP SP3.
I created a new cloptset with exclude filters through the ISC a couple of weeks ago. When I try to modify the cloptset, either by modifying an existing exclude filter, or adding more exclude filters, it behaves OK in the ISC, no errors, it displays the modifications as I expect it to. However, if I go back and look at the server actlog, NO commands were issued to the TSM server to modifiy the cloptset. Close the browser, start a new ISC session (or do q cloptset from the cmd line), and the cloptset is unmodified. Get the same results in IE8 and in Firefox 3.0.15. Anybody have a workaround? I really, really hate doing cloptsets from the cmd line....
