Probably the quickest solution since this is a unique problem unto you would be to possibly rename the spectra to something more manageable. The linear combination fit results can be exported after each fit comparison later. You can also generate a spectrum of the fit and make it one of the spectra in the main screen of Athena. This allows you to compare the spectra you previously fit and then go back to LCF and fit a new spectrum with the standards.

In this window I can see the name of the spectra only partially and this window can not be resized. So my first question is if the "Import from Athena project file" window can be done resizable?
> 2. I'm using Athena to perform Linear Combination Fits of my spectra. As I said, the names of my spectra are quite long, so to see the full name in the Athena I need to resize the window. The resizing works fine, but if I change the "Main Window" to "Linear Combination Fitting" then the window of the program resizes back to the standard size and I need again to resize it to see the full name of the spectra. It happens each time when I'm using "Data menu" to access different data processing features.

> Up to this step everything works fine. Now I need to fit next spectra. So I choose next spectra in group list and then I repeat 2-4 aforementioned steps. I again get the proper fit. The problem comes when I would like to check the fit which I did for previous spectrum. So in group list I simply choose the previous spectrum, but "Fit results" tab is empty. "Standards" tab shows the standards used for fit of second spectrum.
