When I save an attachment in version 149, the filename area is blank and in order to save the attachment I have to manually place a filename with the extension in the file name are of what appears to be explorer. When I do this it saves and opens as expected. This is different behavior to the previous beta version. I am running the October 10 update of Windows is that may be an issue.

Hi @Nev

Sorry to hear about your trouble. 

Please share a screenshot, it will help in clearly understanding your problem and give a clear picture before further proceedings.

Thanks for your co-operation!

When I right click on an attachment to save it to the default Documents folder as illustrated, When I select Save nothing happens however, if I type in a filename with extension in the File Name area, the attachment saves and will open as normal.

Hi @Nev

Thanks for writing back and explaining the scenario.

We have tracked the issue and a fix will be available in the next update.
