TC 8ß23 x64, Invalid pointer operation

[odiwan]

Hello,

on my Windows 7 x64 German, Laptop with WLAN Network, I press ALT-F2 to connect to a NAS drive.

This works fine, but after an other second this screen prompts up:

---------------------------
Total Commander 8.0ß23
---------------------------
Invalid pointer operation.

I will check it, thanks.

1. What kind of NAS is it?
2. When exactly do you get the error? One second alfter you press Alt+F2 and do nothing, or one second after actually choosing a drive?

Hello,

to 1:
NAS is a QNAP TS-259+ actual Firmware

to 2:
I become this error one second after choosing a drive

More Info:
The drive is reconnected very well and shoes he right content in the panel.

In contrast the DriveLetter DropDown Box, is completely empty after I confirm this error.

I never noticed this error in any other TC 8 beta versions

Hope it helps, thank you.

Regards
Michael

Hi!

I experience the same error (with the same stack trace as Michael's) when I connect a USB stick (8 GByte, exFAT) to the computer and press Alt-F1 or Alt-F2 right afterwards. The dropdown drive list occurs and then the error (without doing anything else).

The USB stick itself works just fine. Also a file system check didn't show any problems.

I don't have another USB stick available, but I will try on another computer this evening.

I found the most probable reason, and will try to fix it in the next beta.

Hi. I'm confirming the behavior with (networked) drives [X:, Y:] newly mapped outside TC (8.0beta23/64) via Win32 API. After drives mapped (as confirmed by the "mapping" app), I turned focus back to TC and I clicked quickly on the drive droplist (or more likely used Alt-F1). I suspect the pointer upset may occur intermittently during droplist update "simultaneous" with general list pane update triggered by the re-focus: the current drive was a slow USB drive. I could not reproduce it by un-mapping and re-mapping the drives; perhaps the USB drive data were cached now.
Cheers, Hroch.

I just tried with the new Beta 24. The issue seems to be fixed. Thanks for that one.
