I am running a non-popular windows software with PlayOnLinux and numerical fields like currency/monetary has an error with duplicated decimal separators.
Numbers are displayed as follows (with Brazilian locale):
,200,00
And, if I change Ubuntu's locale settings (to US locale, for example):
.200.00
My question is: How can I solve this problem? or Where can I ask this question if AskUbuntu isn't the right place?
WineHQ.com is the place to report such issues.
