Drives list in My Computer level is not listed by any (known) rule

[bassiliin]

In local browser of FlashFXP when being in My Computer level all drives are listed like randomly even when pressing Name column header which should sort by name. When pressing again then list reverses but still maintaining it's first random listing. It isn't selected by drive letter and not by drive name also. In drop down menu everything is correctly seen as by drive letter (A:, C:, D:, etc). When entering into some drive then all folders and files are sorted correctly by its name.

I attached two pictures also.

Bug or feature?

WinXP, FlashFXP 4.2.0 (build 1732, 1734) Portable
