hi  Vlad,

I think this bug has been fixed for a long time:)

But I am not sure if there is a new release with the newest code.

Thanks for your reporting!

Hi, 

Could you provide me the link on the similar bug where it was fixed. Due to this bug I can't compare files from SVN. As I said I can do comparision if I have downloaded and installed the current PDT 2.2 and have no updated it via "Check for Updates" tool (see step 4). So means it that I should never update my PDT all-in-one version with Subversive 0.7.9 till new PDT will released?

Thanks

Maybe you are right and this bug is duplicate of 326795. But 326795 was fixed a long time ago, but this bug was gone only with last update.  In any way this bug is fixed now therefore I would like to thank you for your work.
