There is probably a reason, but it is unlikely that we will find out. I don't have the impression that Swissmicros is close to the community with informations.

But if anyone with contact to SM is reading this ... please take a look at the link to the DM42 manuals.

Hi,

I flashed the new firmware successfully.

I had hoped that the problem with CIRCT, the electrical parts editor had been fixed, but
it still does not work as intended. I wrote about the problem here:

viewtopic.php?f=17&t=2994&p=20449&hilit=CIRCT#p20449

May be it could be fixed?

Cheers.

Thanks for the note about the DM42 docs; the folder was updated with the newest DM42 manual but something slipped and 41X stuff is shown there. It should be fixed by tomorrow morning (depending on where in the world you live )

The reason for the inclusion of 3.0.5 vs 3.0.6 in DM42 v3.20 is simple. Integration of 3.0.5 began shortly after it was released in July but before 3.0.6 was released. Then the DM42 bugs were traced, identified and corrected. Then the Voyager fonts were improved and verified. Then a completely new Voyager User manual was written, reviewed, re-tweaked and completed. Then summer vacations happened while docs were being reviewed and testing was going on, and then stuff was released.

I really think the negative reactions about not getting the 3.0.6 features, which I've seen no evidence of anyone using anyhow, are somewhat hostile and overblown. Through observation and some insightful guesswork, Didier explained it pretty well, but I thought I'd fill the gaps here for those that were unconvinced.

If the features in 3.0.6 are important for someone, please just say so; "I'd like to use XYZ feature for doing this or that". Also, it would be helpful to confirm that you've worked with the new features (on other platforms) and found them stable and effective for your goals. Just pointing out you've noticed what has not been included is not a collaborative / constructive approach, and is a disheartening response after a lot of work to provide another upgrade.

This problem should have been corrected in the v3.20 release. Are you sure you retested this with the new f/w and had the same problem? If so, please create a new state file, bring a new copy of the program in and try it. If it persists, please post exact steps and a screen shot of the garbled graphic results. It's possible there are some variations of the bug that were not corrected, which only occur in highly specific conditions.

Thanks

I for one is grateful for the update, having spent 30 years in enterprise software, sometimes one underestimates the amount of work required to release an update or a patch. I am not a power user and I certainly do not downplay others desires for the latest and greatest, but in my use case, I am absolutely satisfied with the frequency, currency, and quality of the update provided by Swiss Micros.

Keep up the great work and thank you!

I have checked the CIRCT program with the latest firmware and as as far as I can see the issue you reported is fixed. Here is a screenshot to be compared to the one in your report:

So as Bob mentioned if you still see an issue with the latest firmware, please provide the detailed steps to reproduce it.
