Saving a second project on Windows 7 64bit and explorer issue

[astrospotter]

I don't have the full formula but I think this is a way that PixInsight will be unable to save a new project in the same location as a prior project.

I have current PixInsight 1.7 that says no updates required at this time as of just before this note entry.
It runs on 64-bit windows 7 Ultimate and is the 64-bit executable.  I have 8 gig memory and many gig available at the time of this fault.
have a project fully saved from some earlier date and open it in PixInsight (opening of the prior project may not be part of the formula)

I work and save new .fit files and use many tools.   Then I wish to save the project but realized I wanted to save a NEW project.
So I save the project and specify the same folder where the prior project was saved with success and also where there is an open windows explorer at this time.

As I do the save many files copy to the project subfolder but I get some form of cannot save message that indicates file is in use.   Just now I closed all windows explorers and tried save to new project and it worked.

So I feel if winodows explorer is open to the folder where I will be saving a new project is how we get to this error.

Hope this helps.   It happened 3 times prior to this all failing and on two different projects but same basic workflow.

I realize I don't need to save a new project and that that uses duplicate disk space but that I don't care about and in fact DO want a different project name for the environment I leave everything in to keep the project cleaner and have a past history of 'checkpoint' more or less in the older saved projects.

Thanks,
Mark

I also wondered what would happen if I save a project to the same directory, since a project always consists of a file + directory containing data. I think it is not really a good idea to create a second entity (the directory) based on the name of the project file specified by the user. This PI behaviour is quite unusual. I think it would be better to save everything into one file, or to let the user specify a directory name only.
