Blanker module gets de-blanking signal...

Hi!

I´m trying to rework the "Commander" blanker module. I experienced some strange behaviour with it, and I can´t find the cause of it. Maybe somebody here could point me to it?

When running the Commander module, all seems to work normal. Preview works, fullscreen preview works. No sudden de-blanking occurs.

But as soon as the module should work as a blanker, it gets a signal and de-blanks right after drawing one frame displaying the actual time. The signal seems to be 0x80000000, and its the signal it gets when in fullscreen preview mode, too (but "normal" operation there). I have no clue where this signals stems from.

The interesting part on this is, that this behaviour is inherited by all blanker modules used after Commander (until reboot, that is. As long as Commander wasn´t active, all other modules work ok). Is something known about such a problem? Maybe some initialisation error in Commander? Something going wrong when it is loaded? As there is good documentation about the screen blanker engine missing, I don´t know where to search for the bug :-(

Thanks in advance.

Edit: Ok, pls forget it.

It´s a problem with ScreenBlanker prefs. I don´t know if this bug is known to the dev team, but I wasn´t aware of it. Every blanker behaves like this, after the ScreenBlanker prefs program was used. After a reboot and by not using the prefs, all blankers work fine...
