Hi there, everything nice, everything cool, except one thing: e.g I am working on wireframe on the Mac. If colegue opens it on the Ubuntu or Windows, all texts are displayed different font sizes , different text boxes heights etc. Same happens if from colegue with Ubuntu I will open project on the Mac.

Hi Andrew,

WireframeSketcher defaults to system font but you can change that in preferences. For cross-platform compatibility you can choose Comic Sans or Arial which are the most common. Note that for existing screens you'll have to adjust the font in Properties View. Click on the empty canvas in the editor and you'll see screen properties including the one for font.

Let me know what font worked best for you!
