Unable to input colon in textfield

Hello forum!

We got a call today from a customer saying she was unable to input colon “:” in a textfield, instead it would turn into a “>”.

My first thought, since she’s on a PC, was that she probably had switched her keyboard layout from swedish to english which would indeed make the colon turn into a “greater than”. But after some investigation this happened on every pc I tested this on, and outside flash the inputs were correct. I am able to copy-paste a colon into the textfield.

I also tried this on a pc with Windows 7 with a strange outcome. The first input became a “>”, but after that the colons appeared correctly. After reloading the flash it worked from the first input.

Note: the problem seems limited to Firefox

I hope someone recognizes this and has a solution cause I’m all out of ideas here!
