I've googled it and read a number of angry posts concerning this issue. If I IM via Skype on my Mac it does not matter if I delete chat history, as it still appears on my Skype mobile device. The notion that I have to delete Skype from my mobile and then reinstall every time I use my Macbook is just inconceivable. I've deleted cache but that does not take care of the problem (as some online have claimed will work). Please, someone, tell me I'm in error (and how) or that a newer version of Skype is going to fix this issue as my business and personal privacy should not be so easily violated by anyone (with good or ill intentions) who might access my phone.
