1.7.2 - viewer/browser - open with associated editor - path truncated at space

[user0]

XnViewMP 1.7.2 64bit
Windows11 (23H2), display resolution 3840x2160, win scaling 150%

Browser/Viewer - open with associated editor (MSPaint in my case)
path param is truncated at the first space

To reproduce:
0. make the following file/folder: "c:\a b c\a b c.png"
1. open file in Viewer or select in Browser, press F4
Paint "file not found" error message appears, showing the path truncated after the first space
(c:\a.png)

there is no such issue when using Edit command in win file explorer

no problem here, Paint is opened correctly
