--- Comment #8 from Shlomi Fish shlomif@shlomifish.org --- Hello Yaron,
(In reply to Yaron Shahrabani from comment #7)
Hi Shlomi, Thanks again and I'm sorry for all the trouble but do you think you can report a bug about that and also report your findings in the AppDB link I added earlier?
Sorry, I won't do that. I'm not an active user of Viber (it's the first time I recall hearing about it) and I have no interest in seeing its Windows version supported under WINE. So I guess you're on your own now.
