Trap 25 on start

[Bernhard]

Since today, I cannot start Blackbox anymore In my (restricted) work environment and I get a Trap 25, see attached Trap Window:

TRAP 25 is

Code: Select all

ASSERT(pl < pr, 25);

which, presumably, wants the page left to be less than the page right (margin or paper size ???).

Does your installation automatically open any documents on startup that can be (temporarily) moved?

[Bernhard]

no, it does not try to open any document (except the log viewer ofcourse).
The strange thing is that this occured over night without any clear changes in between.

[Robert]

All I can suggest is down loading a fresh copy and trying that.

[Bernhard]

forgot to say: I am still using 1.7.1 (since I have to apply for freeing Blackbox from being locked out by AppLocker).

[Robert]

Youy can down load a fresh version of 1.7.1 from http://blackboxframework.org/index.php? ... page,en-us to check if your version has somehow got corrupted.

[Bernhard]

All I can suggest is down loading a fresh copy and trying that.

I tried running from a freshly downloaded and unpacked 1.7.1 zip, but this does not change anything. Still trapping. Very strange.

I started reading in System/Mod/Documents.odc and noticed that StdDocuments.SetView reads stuff and uses it from some kind of printer configuration. So I reset the default printer to "MS Print to PDF" and now Blackbox starts again. Maybe this helps somebody else ...

After starting successfully, what happens if you select the printer that was in use when it did not start successfully abd try to print something?
Maybe you can get a more informative stack dump then to see what is going in.

hmm, the problem is/was that I was not able to determine, which was the current default when the error occured and it was due to corona a virtual machine via RDP connected to an USB WinToGo stick booted locally. The local BB on the WinToGo stick had no problem, only the BB on the remote virtual machine.

Update: no success, this appears to be an unreproducible error. I tried setting all available printers as default, but in no case BB trapped.
