first of all I'm happy that the software, even in an ancient release, seems to work perfectly for you!
Naturally, if you have questions, we'll answer them.
But we won't create fixes for the 2.7 release, unless the bug is present in all releases.
(In such a case it often isn't much work to do an extra backport and to create the rpms).
Basically the rule is that we support the latest release and the two previous ones. (Currently 2.10, 2.9 and 2.8).
Hence the current state of the 2.7 is that we'll help but there won't be any 2.7 specific fixes.
From that perspective it is recommended to upgrade to a somewhat newer release (I'd say at least 2.9).
Upgrading schedulix isn't hard. If you've installed from rpms, the upgrade runs automatically.
And if you've installed it entirely yourself, the procedure is nearly the same as the original installation.
If you need help, just drop a question here.
If your company insists on using 2.7 and needs support, we'll need to negotiate (not here) about the height of the motivation.
It's not impossible, but it'll cost a few Euros.
