Fonts and Vista

Hiya (yes its me again)Has anyone had any issues with Lectora 2007 and Vista?Building content in Vista does not replicate the same in XP or 2000, and when you amend in XP and then try and display in Vista, it comes up with sizing issues - causing text blocks to appear wrongly sized or spaced.Is there a way of detecting an Operating System and getting around this? Is this only common to Windows? How about Mac and Linux?Thanks
