Print Jpeg and TIFF not multipage

I have installed the last version 0.9.9, and I have found this problem:

 

If I select Jpeg output for a document with more then 1 page, it create only one page with %d as last part of the name, and the page in not opened from the default viewer.

 

If I config "Document" - "One page for file", and then select TIFF output for a document with more then 1 page, it create a multipage tif (instead of one for page)  with %d as last part of the name, and the page in not opened from the default viewer.

 

Is there any other parameter to config to solve this problem, or is it a bug?

 

Ca you help me?

Can someone help me?

I have installed the last version 1.2.1, and I have found the same problem:

If I config "Document" - "One page for file", and then select TIFF output for a document with more then 1 page, it creates a multipage tif (instead of one for page)  with %d added at the end of filename.

Is there any other parameter to config to solve this problem, or is it a bug?
