This bug has started happening recently.
I think it started with Xplorers v2.40, didn't have the bug in v2.39.
Basically, I can be typing a sentence, and then when someone pops up a trade window, my text becomes highlighted. Since I'm in the middle of typing, it overwrites and deletes all the previous text leaving a fragment from the end of my sentence. Very annoying!
Probably best that when a new window opens, the text is not automatically highlighted, that should fix it?
I think also my first character is highlighted, and my second character overwrites my first character (e.g. typing 'hi hf' comes out as 'i hf')
In the previous version there was a different bug that the first character appeared twice (e.g. typing 'hi hf' came out usually as 'hhi hf'!)
Really weird! Can anyone explain where all these bugs are coming from? I think I've had them on Macs, but possibly not on PCs, however I haven't used a PC for a couple of years, and am not going back now
