Bugs in Solve command.

[Helge Gabert]

It would be nice to make a hardware, firmware update available soon (especially since this, and similar problems involving solving with symbolic variables, worked in some firmware versions prior to 10637).

Interesting, too, that solve(-x-e^x=0,x) with only one variable still results in the error message "Unable to isolate", but solve(-x-e^x=0,x=-.2) works!
