OS: Windows 10 - 64bit
After a crash of XnView MP the Kolor Crash reporter appears and allows for uploading crash info. The Crash reporter allow for deleting the report. After deleting the report you can still upload but instead of uploading a message box "The server seems to be down." appears.
Effect: Confusing/unexpected behaviour
1. Produce a crash in XnView, e.g. by performing the steps described in 0.84: Crash when high quality zooming b/w image
2. In Kolor Crash reporter, press "Delete".
3. The crash report is deleted.
Actual behaviour: After deleting the crash report the "Upload" button is still enabled.

Expected behaviour: After deleting the crash report the "Upload" button should be disabled.
Note:
I think the user interface of the Crash reporter should be partly redone. There are far too many buttons for this simple workflow of reporting a crash. Two buttons "Upload" and "Cancel" should be sufficient and after a reporting the successful upload in the message box the crash reporter should close and the bug report should be deleted automatically.
