Hello, I'm having a problem with the XChange PDF viewer within Firefox: When annotating a file outside of Firefox, I can save the changes and have them reappear when I close and re-open the file Doing this inside Firefox, I cannot, it appears that the files are saved, but they do no reappear on re-opening. This is true even when annotating a file that is opened from my hard drive (as opposed to opening it from a website) Doing this inside IE, it works properly. However, I need to use Firefox here at work instead of IE or XChange separately. I believe the problem lies in the fact that when XChange/FF open a pdf inside FF, a file is created in C:\Temp and the changes are somehow being lost here. Interestingly, if I take the file opened within FF and open it in XChange outside the browser (by using the button in the bottom left of the viewer pane) I _still_ cannot save my changes, and I now get an error message along the lines of: ‘Error saving document to “c:\Temp\pdf38.tmp”: Error [IO subsystem]: Invalid access mode’ where 'pdf38.tmp' is the name of the temp folder created when the original file was opened within FF. I didn’t have these problems a few months ago, so it’s something to do with the new versions of XChange and FF. Please let me know what you can do to fix this. I really like using XChange, but if this can’t be fixed I’ll have to switch to something else to do my work. == This happened == Every time Firefox opened == Reinstalling latest versions of FF and PDF X-Change
