I have had only the most minor problems with GraphicConverter since first purchasing it at around v. 3.8. But when I tried to browse a folder containing 147 large image files with v. 5.7.2 - it crashed immediately.

I emailed the crash log and relevant info to Lemkesoft. Within HOURS I got Thorsten's request that I try out a "debug vervsion" of GC and report results.
I downloaded and installed the debug version, put it through over one hour of testing (not just the browser functions) and reported back: It works perfectly.

I also subscribe to the Yahoo! GraphicConverter User Group - I observe the same rapid response and solutions there - even to 'the dumbest questions.'
Further, Thorsten is constantly responding to "requested features" which add to GC's capabilities.

It just flat-out amazes me that this developer is so dedicated to quality and customer support for a product which costs so little and performs it's "advertized functions" so well. Thorsten Lemkie is the best software (for Macs) developer I know of - possibly the best one on the planet.

Note: No developer can or should respond to those who just want to rant and complain. When a problem arises, it is the user's responsibility to provide complete, non-insulting feedback. Only THEN can a developer's responsiveness and performance be judged accurately (and fairly).
