Alrighty ... I'm pretty sure that I have the smoking gun on what's causing the problem. After some brainstorming and some testing to confirm my theory, here is what I figured out.
I don't know about the rest of y'all, but when I do any downloading, especially software Apps, I like to RENAME the file name right on the spot to a specific format to keep with my meticulous organizing of all my files. Well, apparently Maxthon Cloud's Download Manager doesn't care for ANY renaming of files about to be downloaded. Apparently Maxthon wants and expects the file name to be kept INTACT as is. If the file name is kept intact exactly as was displayed by the Download Manager, the download will go fine and the downloaded file will be a good, working file. IF on the other hand, you change the file name from what the Download Manager displayed ... then the results will be the infamous blanks, non-working files with generic icons like what I experienced.
That said, am I missing something? Is there a Setting somewhere that will allow me to be able to download files with Maxthon while changing the file names on the spot and have the files not be rendered useless?
I will go post my suggestion in the Features Request thread. I don't know what the chances are of the change being incorporated into Maxthon. But, as it stands, the way I do things, this issue is quite a wrench in the machinery. I sure hope the change is incorporated because as I alluded to before, aside of this issue, there have been some pretty impressive positives that I have really liked about Maxthon Cloud.
