1.9.2: No new files in browser after refresh

[moropus]

XnView: MP 1.9.2 64 bit
OS: Windows 64bit

New files are not shown in folder, especially big ones, even after manual refresh with F5

To reproduce:
1. Open Browser
2. Start a process which creates a big file in the folder or it takes a lot of time, eg Export to Tiff in Photoshop or scan to a file.
3. After the process is complete switch back to Browser
Actual behaviour (bug):
* No new file is present in Browser
* F5 doesn't help either
* Only switching to another folder and back actually shows new file

Expected behaviour:
* New file is present in Browser, F5 refreshes the folder

Do you use 'Filter by>All'?

[moropus]

Yes I do by default

if you add a smaller file, it works?

[moropus]

With smaller files it works most of the times, but sometimes doesn't even with jpegs.

i've tried with a picture 7000x4000 in tiff, but file is correctly shown in thumbnails

Maybe ini file can help.
