Hi everybody ! I'm back ;-) I've found why WTLib crashed ! [Idea] In fact it's always linked to font files. I dunno why but the application cannot load a proper japanese font on startup so the application looks for Wingding.ttf file in order to display smileys instead of characters. Here is a screenshot about the smileys displayed ... [Image: http://img258.imageshack.us/img258/3639/wtlibusingwingdingfontiv1.png ] But this file is missing in the .wine/c_drive/Windows/Fonts folder. That's why the application shows a popup alert (that cannot be read because japanese font is not displayed) and stop, if we install the application from scratch. [Image: http://img258.imageshack.us/img258/2631/wtlibjaperrmsgtn8.png ] So my first question is : is there another linux font that i can install to replace the wingding one? Or is there a solution to avoid this problem ? Fortunately, WTLib can use a specified font file under its "preferences" menu. So I'm now able to see japanese content except some controls like buttons, menus or tree view 's elements. Here is a screenshot [Image: http://img218.imageshack.us/img218/7872/wtlib07japsv2.png ] So my second question is : is it a bug ? Maybe there are some tips to do in order to fix the display or maybe this is actually a missing feature from wine controls ... Thank you for your help. Aurélien.
