I'm not sure if I am experiencing the same issue, but I have noticed that PDFCreator 1.0 does not 'remember' the last used directory for saving the pdf when I change it. 0.9.9 used to update the remembered directory as I saved files. It is interesting that 1.0 seems to have 'inherited' the last directory I saved to using 0.9.9 as its default directory but does not change this when I change the directory somewhere else.
I have installed the new version 1.0 and i can confirm that pdf creator doesn't remember the last saved directory as the version 0.99 does.
The new version 1.0 will always propose the "my documents" directory for saving, and changes in settings does nothing. After saving the profile in .INI file, i saw that the last saved directory was t:\\traces (it's correct), but PdfCreator does not use this value for new files.....
