Save as (pdf) interrupts regular Save process
Accidentally we discovered that when you're too quick with the Save As after you've Save(d), the Save process is interrupted/overruled by the Save As process and the file is not Saved.
Here's the (reproduced) situation:
We sometimes have to make small (textual) edits in our Illustrator files, after which we need to produce a proof pdf for additional checks.
We edit the .ai file, press Save (to save the changes in the .ai) and immediately press Save As, change the file format to .pdf and save the document as a low res pdf.
When you then close the file and re-open the .ai (which you first saved) from which you made the pdf, the changes made are not saved in the .ai file.
It appears that the Save As (pdf) command cancels the Save (ai) command.
There is no notification, which you would expect and which was the case in the previous versions, that you cannot save as, because the file is being saved.
Is anyone else seeing this issue?
