XnView Software

I have just confirmed many times that if you open two separate programs and one of them renames any image in the browser, the program will pop up immediately with the following error.

P.S. ver1.9.3 64bit windows

I can't reproduce. Please send us the crash dump and specify this thread's link or email

Here are the steps I took to reproduce the issue:
1) Open XnView MP and set the browser to C:\My Pictures.
2) Open another XnView MP and set the browser to D:\sample.
3) In the second browser, copy any image from D:\sample to C:\My Pictures in the first browser.
4) Assume you select error.jpg. Now both browsers have the same image with the same name and content.
5) Recopy error.jpg from the first browser and paste it into the second browser. When prompted to rename it, use the default name error copy.jpg and press OK.
6) Now select error copy.jpg in the second browser, press F2, rename it to error1.jpg, and press Enter to display it full screen.
7) error1.jpg is not displayed. Pressing Esc to exit the second browser crashes and an error report pops up.

Thanks to your detailed description I can reproduce the problem.
