[Slow response when using features]

It doesn't seem like the operation of PDN would just change all by itself. You should investigate what's going on

with the rest of your computer. For instance, some program or Windows service doing some heavy work in the

background, or perhaps a hardware glitch creating an "interrupt storm" could be causing the symptoms you

describe. The Windows Task Manager will give you lots of information about that kind of stuff.

[Removing white around images]

Using "View Image" in Firefox, there is NO white background. Nevertheless, the image filename has a ".jpg" ending

when I "View Image Info".

[Problems with Paint.net v3.5.10 Freezing]

Might you be just a little more specific about what you are doing when the lag/freeze occurs? You know, stuff like size

of image(s) you're working on, number of layers, etc.? How much memory is being used by paint.net vs. memory

available and in use by other processes (Task Manager tells All!)?

There are rather regular posts about those rogue websites on this forum, but I can't say I've ever seen one. Perhaps

because all my browsers are equipped with comprehensive ad- and malware-blockers.

[normal way to print?]

Yes, it is.

[Thank you for this great app but..]

No one needs to install Firefox to get the superior browsing experience that AdblockPlus affords. Internet Explorer 9 (a fine browser, IMO) has a feature called

Tracking Protection Lists, and there is a TPL created by the author of EasyList, one of the main subscription lists written for AdblockPlus. With that installed, the

PDN homepage is ad-free, and, at least with the sort of websites I frequent, there is very little difference between pages viewed with IE9 or with Firefox with AdblockPlus

installed.

[Paint.Net icon disappears from Start>All Programs menu]

Strange indeed. Do you have your Search facility set to ignore "hidden" files? I ask because your search for "paint.net" should also have turned up

the paint.net folder in your appdata\local user profile folder. I believe Acronis will allow you to mount your backup images, so you can see if the

paint.net shortcut has indeed been copied to your backup. If you are not in fact "imaging" your c: partition, but using a file-based backup, perhaps

Acronis is using the Archive bit/file attribute and paint.net is creating the shortcut with the bit not set? Do you have anything auto-running at bootup/login

that might possibly be removing the shortcut?

[Paint.Net icon disappears from Start>All Programs menu]

The items in the Start Menu All Programs list are the names of .lnk files (aka shortcuts) located in either the

all-users start menu folder (c:\programdata\microsoft\windows\start menu\programs\ usually) or your user-specific

start menu folder (c:\users\<yourusername>\appdata\roaming\microsoft\windows\start menu\programs\ usually).

Evidently you are losing this file somewhere in your backup/restore procedure. As far as I can tell, by default Paint.net creates

a shortcut in the all-users start menu when installed, removes it when uninstalled, and does not mess with it otherwise. There

are no registry entries involved. Of course, if you specified a per-user installation of Paint.net, then you would not have its icon

in your All Programs list unless you were logged in as that user. I would suggest looking in the Acronis support forums for help on this issue.
