SED debugger forgot names of variables

What should i do to command the SED debugger not to forget name of variables what want to debug?
Each time when i start SED (after a normal close or crash) i had to type in again and again the names.

Edit: My system is WinXP, A7 Comm.

And SED forgets last opened files. As long it runs, I can choose last files in File-Menu. After shot down, last used files are forgotten, too. Both forgotten things are no bugs, but could be nice features to have
