vhdl - Reset modelsim editor to the default one -

i want reset editor default 1 in modelsim don't know how.

when double click on project opens in notepad. tried change value of editor variable "edit preferences" tab didn't work.

i tried change windows settings open modelsim.exe , worked first project only, when want open project enters loop keeps opening modelsim again , again. right way so?

i bypass problem typing "edit filename.vhd" without double quotes in transcript (that window looks console @ bottom of modelsim). not radical solution.
