lineHeight different Mac vs. Windows

I think that the size difference is related to the specific font used. Georgia is displaying slightly wider in Windows than Mac. Helvetica seems pretty consistent. A Chinese font I use is much smaller in Windows.

Changing Georgia from 16 to 15 is too drastic a change for me, so I need to keep the font size the same.

I can’t set the textHeight since I have to set fixedLineHeight to false so I can display thumbnail images within the text.

I suspect that the space between lines when fixedLineHeight is false is determined by the specific font metrics, something LiveCode can’t or doesn’t want to override. I haven’t done a test of various fonts comparing the Windows vs. Mac “free” line spacing. Maybe there is a constant among them all…

At any rate, do some experimentation on Windows to see if you can adjust the flow using textsize and textheight, or by experimenting with different fonts.
