I hope I’m in the correct forum. If not, feel free to move me.
First of all I love my High Logic software! However, now that I have Vista when I work on a font it won’t save it. I’ve lost so much work because of this. Everytime I hit ‘save’ I get a pop up that says it can’t save because the font is being used by another program. It isn’t. I don’t have anything else open at the time. I did a search here and tried right clicking on the icon and using it as the administrator. No luck. The program works fine. I just can’t save any changes when I’m finished. Everything was fine in XP. Any other suggestions? Please. I’m begging here.
Windows itself can also keep a font file open, so closing all other software doesn’t always work. Do try to save it in another folder, restart Windows Vista, and then install the font through MainType. Do let us know your results.
When you hit ‘save’ and save all’ it won’t let me do anything because it says it is already being used. So, I clicked on ‘save as’ and sent it to my desk top and dragged it to my font folder in the computer. Ta-da! Sort of a pain and a long way around but it worked.
I could also open a brand new font thingy and copy and paste the fonts of an old thingy to the new one. Then rename the new font folder, delete the old one and drag the new one to my font folder in the computer. Time consuming but it worked.
The only problem will be when I want to add or change something, I’ll have to make a new folder, send it to my desk top, delete the old folder, and add the new one. It beats losing all of my work though.
I guess you can tell I don’t know a lot about computers! 
By default even Administrators run their applications with limited privileges in Windows Vista, so I guess that’s why FontCreator fails to save (font) files to Windows folder. It is best to work on a copy outside of Windows Fonts folder, and then use FontCreator’s Install Wizard.
How do you work on a copy outside of Windows?
Everytime I change anything I have to copy and paste all of the fonts to a new folder and save that folder to my desktop then uninstall the old folder and install the new one from the desk top.
This all worked so well in Windows XP. Maybe I’ll go to my son’s house and use his computer computer and be done with it.
