I have yet to use an XnView software (Linux or Windows platform) which i found not to live up to its claims. I must admit that I prefer XnView Linux (v 1.7) to the Linux-native image viewers because of its extensive image-format support, including PSD and PDF, in addition to its ability to save in ICO and GIF formats, and the PNG alpha-channel support is excellent-- however, i do often prefer to use XnView 1.9x (a Windows-only version) on Linux-- run under "WinE"** because the Browser includes a "Favourites" feature, and offers many other nice luxuries for the user-- yet unavailable in the XnView app designed for the Linux O/S.
It is unfortunate, however, that I have encountered a problem with v.1.9x under WinE. i've tried tweaking the Options in as many ways as i've had the urge to do so-- and i've not had any success in regaining a preferred setting. Please view the screencap to better understand my plight.
I appreciate any suggestions you might have. Fortunately, v.1.8x (also a Windows-only version) is fully operational, and offers many of the 1.9 features, but i'd like to fix this problem.
THANKS!

WinE is a free "Windows Emulator" software distributed w/ Fedora (and many other Linux distros). winehq.org for more info
