Hi there
I am using Scribus for simple editing tasks. Basically I digitally snip PDF pages together. My workflow: generate PDFs in MS Word (and other applications), add and crop them in Scribus inside image frames (typically 2 or 3 pages, containing 5 to 10 snippets, no images, mostly text and math formulas), and export everything as a PDF.
With Scribus 1.4.3 I typically get file sizes of 200 to 800 KB. Now I tried out Scribus 1.4.8 and get file sizes > 100 MB, or even > 1 GB for the files described above. I noted that the "embed PDFs" option is grayed out in the PDF export dialogue. Is this the reason for the huge file sizes?? How to get that option active again in Scribus 1.4.8? Any trick to get back to the "normal" file sizes?
If needed, I can upload a test file that reproduces the problem (114 KB on v1.4.3 and 660 MB on v1.4.

. I am working on Mac under OS X 10.12.6
Second question: Is there a Scribus version for Mac OS X 64 bit versions (namely OS X Catalina)?
