OK, allow me to rephrase the question, if you will: Do you think it is acceptable that one the main Stardock's products has not had a stable release in over 2 & 1/2 years, has such a log of documented issues and has not been officially declared compatible with neither Win 7 nor 64-bit architecture?
Desirable? Maybe not.
I know of lots of programs which were released years ago....that functioned quite well...then....that do not now...and have had no further development either public or private.....all outside my control/influence...Sysmetrix is one.... Litestep [has always been one]....then there are literally HUNDREDS of other skinnable applications that have not seen renewal in years.
Would you like me to rattle them all off?
Whether or not Stardock releases revised versions...or limits possible beta testing to one group or another is all entirely outside my sphere of influence, and no amount of verbalising of frustration will likely make a huge difference.....unless perhaps it is from those who decide SD policy.
Now if end users are using a proggy, any proggy within an OS for which said proggy was not intended/developed then they should rightly expect "issues".
As for not officially being declared compatible with Windows 7 and/or 64bit that is clearly because there has been no released update of the proggy for X number of years....quite logical, really.
If attempts to use it on an unsupported OS fail or cause issues then I'd probably not use it.....
...until such time as there is an appropriate release...
