Question : toad

I am having a strange problem with toad. It used to be fine until today ; It will let me type
words and stuff but will not let me use the backspace or any arrow keys( up, down etc) or page up or page down.
All that I can do is to type and if I typed something wrong ; so have to use backspce or delete key to delete it , nothing happens...
Any thoughts on this?

Answer : toad

Try this.

Close Toad.
Delete "plsqlkeys.bin" from your temps directory.
Reopen Toad and see whether those keys now work.
