Well, it looks like I have egg on half my face.
As best I can determine, this issue came up because a new file started downloading just as I upgraded to AB 0317, it looks like the 'truncated filename' has been there all along.
The problem seems to occur with NZBs that have embbeded spaces in the segment posting titles (instead of periods (.) or underscores (_)). AltBinz properly downloads the files, it's just the segment entries in the expanded download queue frame that have truncated names, while the name field in the active thread status frame is shown properly.
I ran a couple of experiments with an edited NZB where I replaced the right hand (end of name field) spaces with either underscores or periods and AltBinbz then displayed more of the segment name in the download queue. It always seemed to truncate to the left of the first embbeded space for the NFO, RAR and zero length PAR2 files, the actual PAR2 correction files always displayed the full name (note: I have 'small par2' unchecked in the import as paused option, everthing else is checked).
In case it helps, I have uploaded a foreground window capture to Hotfile (short_name.jpg)-
