Error downloading attachment which had been uploaded by myself

[Ulrich Hinze]

Hi,

 for unknown reason I cannot download or view attachments (pdf) from a task which had been uploaded by myself a couple of seconds before in one specific project.

In a different project the same attachment works perfectly fine. Upload -> view -> download -> okay!

I checked my permissions in both projects but they are identical.

Any ideas? Help would be greatly appreciated!

Thanks

Uli

Sorry, error in the subject: correct is "... which had been uploaded ..." 

Corrected by myself!
