#33 CRTL+X and Save problem

[Anonymous]

Hi,

When I'm typing a expression in the main windows if I
press CRTL+X it gives me an .NET error.

And I need to close the program, to I open it again
to continue using.

Another problem is when saving the file, if I do not
press 2 times enter it will save the file and erase
my last modification....

Thanks
