File in use error

Sometimes happens that pdfprinter does not complete print process because destination file is in use. That issue was not present on previus versions (<1.7).
I'm using version 1.7 on windows server 2008R2 in server mode. There is just one istance
of process running. 


does this happen randomly, or only when printing lots of files in a short period of time?
I remember another user having the same issue and for him it was a timing issue which could be fixed by adding sleep time to his script.



I have finally found the issue. When installed pdfcreator add link to autorun so there where more than one instance consuming print operation. Now using one instance only via srvany its alla right.
It happens sometimes that a print were losed but this is another question and it happens in all prevoius versions.
Tks anyway.
