TDE Version 3.0, like PDE before it, has a bug in the Watch window. Watch an absolute address, ie, for the Add Watch you enter "!xx" where xx is the hex address in RAM you want to watch. This displays ok. Exit TDE, then start it back up. When you view the Watch window again, it forgets for these absolute addresses what you are watching - it says "not known." While you're at it - could you please add a cross-reference listing to the CVASM .LST files?
