Still, a new version causes or can cause havoc for developers.
The question can also be raised as to how much of a "heads up" the SM2 developers gave to 3rd Party Software Developers such as Piriform so that they could "anticipate" where changes to a program (SM 2) would impact their software applications.
In my case, I am using (trying to use for over a month now) SeaMonkey 2 and had also begun the process to evaluate some of Piriform's products (many of which were downloaded over a month ago) but have held off waiting for a compatibility update for SeaMonkey.
As such, I and possibly others, have held off on any real use of their (Piriform) products until they have "accounted" for the new or current SeaMonkey iteration.
In my particular case, I did not have or use SM 1.x due to multiple issues in switching from Mozilla 1x to the early versions of SM (at which time I simply gave up on the early platform iterations) but was and am a "fan" of the concept of the "old Netscape" and/or the Mozilla Application Suite (which I had used for years for the majority of my online browsing until I was simply "forced" due to response and security issues to migrate to other supported platforms for routine use).
In short, if Piriform is going to adapt CCleaner and their other products, I certainly would appreciate a heads up as to when to expect this might be accomplished.
Alternatively, if they choose (which is their perogative) not to support it or make allowances for it - would appreciate a heads up also.
In light of the little I have seen via e-mail updates or read online in recent weeks - Piriform seemingly has little or no desire to make adaptations for the SM 2 platform to accommodate users or potential new users of their software - or did I miss something?
