Bug report on closing preview

[acheton]

Hi Don

I'm getting a bug report running the latest beta 21.10.0025 whereby when I preview a PDF and close the preview window I get a .NET error. Details below:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I've confirmed that this also fails on another machine too with the same build. Closing the preview window fails using either CTRL+F4 or [x] fails. In addition pressing Page Down within the preview causes the same error.

Hope that helps

Cannot reproduce. Is this a new problem?

PS: Why are you using the 64-bit preview anyway?

I reproduced this crash too:

For me the MDBU worked fine a few times, preview worked fine, then when I went back and did MDBU again, I got the crash

2) Why are you using the 64-bit preview anyway?

Is this related to the context menu bitness? I use the 64-bit context menu because I have the 64-bit version of dbPoweramp installed and I use its context menu items constantly.
If your question is not related to the context menu bitness, then I am unaware how to change the bitness of my preview?

Configuration | Other | Shell Integration | 64-bit Windows | Use 64-bit preview handlers for preview

[JLoftus]

just unchecked that option and same thing happened, previewed twice fine and on the third time it crashed with the same error dialog

[highend]

And which preview handler is used for .pdf?

It fails whether on or off.

In the next beta, when this happens again, show the debug log by running this through the XY address bar:

Code: Select all

dlog;

Here you go, doesn't show much:
