Hello,
Well this sounds like something related to the latest update where I fixed broken dialing to the dial 10 using Ctrl + 0 short-key.
But opening dial number 10 should happen ONLY if you have "Ctrl + Number for Group Speed Dial" add-on installed and only if you press "Ctrl + 0" or "Alt + 0".
Could you please send me the list of add-ons you have installed to my support e-mail?

Anyway this sounds quite bad, I think I know a way how to fix it (but still I would like to know the cause first), I will probably release the fix in few hours.

Thank you for reporting it (but please, use my e-mail next time, it's easier for me to track bug there).

Have a nice day :)

Best regards,
Juraj Mäsiar
