If I use linear mode display, I cannot see what someone is replying to.
If I use topic on threads with pages of replies, the message tree will not keep the item I selected on screen.
The problem is the web page height does not adjust depending on the browser window size.
So you have to use the browser scroll bar to scroll the page down so you can see the area of the tree you selected.
This problem is easily handled by an interface with two scrollable windows on the page.
The windows change size so they never extend below the browser height.
This was the default way Outlook Express and Forte Agent work, and its been around forever so Autodesk should have looked at it when choosing a web only interface.
I guess if you won't fix something that isn't broken, the next best thing is unfixing that unbroken thing.
How about a re-fix, Autodesk?
