I installed pdf creator v1.3..2 and it didn't work. When I use a Print dialogue from Firefox the printing progress bar comes-up and that's the end of it. No PDFCreator dialogue to let me save, etc. The test print didn't work from the Options dialogue either.
I uninstalled and installed v1.3.0 that also doesn't work for me. But at least the test print worked, but not with real programs. I rebooted the PC between installs and deleted all program files, etc.
I have since reverted to v1.2.3. This version works with Firefox.
I'm using Windows/7 64-bit; and tested printing with: Firefox v9.0.1; Scite v3.0.1, MS Word 2010.
I will try the versions following v1.3 for pdfcreator to see if this problem goes away; I can work with v1.2 for now.
