I changed CAPTIONBARHEIGHT:SIZE to 21, but dont work for me on 96DPI, work only 196DPI
With 196DPI works even without changing the CAPTIONBARHEIGHT:SIZE to 21, but my system is in running 96DPI and not at 196DPI. I do not intend to add extra buttons for each DPI, anyway adding the Glyph 196DPI function normally there are no problems. You could test your system just by changing the image in 196DPI without changing the CAPTIONBARHEIGHT:SIZE to 21, and tell me if the Glyph normally appears?
If appear, no have problems, I use this way, the important to appear the same on all systems, even if there is a bug in the theme.
