I have recently installed additional Helvetica font that was required by some .PSD I needed.
After I while, I have noticed that font has changed on both IE and Chrome browsers on some pages. Because I didn't like the change I tried to delete the font from Control Panel\Appearance and Personalization\Fonts
Unfortunately I wasn't able to delete the font and did receive this message:
Delete Font: Helvetica cannot be deleted because it's in use.
I have tried by closing all programs but I just couldn't delete it.
If you have the need to disable Internet Explorer welcome Page for All users here's how you can do it:
It can be done on a local machine using registry or Group Policy for wider distribution.
Open regedit from the Run prompt and navigate to the following section:
HKEY_LOCAL_MACHINE | Software | Policies | Microsoft
Create Internet Explorer folder and under it Create Main folder.
If you want to prevent opening of PDF documents within the browser you can do this manually on each machine by opening Internet Explorer | Settings | Manage add-ons
As you can see Adobe PDF add-on is not visible, not even if you select to show all add-ons
Therefore, in the left pane under Show select 'Run without permission'
Select Adobe Reader and click Disable.
If you are using Simple Image Gallery plugin for Joomla 1.6, 1.7 or 2.5 you might have teh following issue.
On published image thumbnails you can see "CLICK_TO_ENLARGE" message instead of "Click to enlarge"
Also when you click on the image from the gallery a pop-up is opened with the following message "JW_SIG_NAVTIP" instead of navigation tip.
The reason for this is because 2 .ini files for Simple Image Gallery plugin have couple of capital letters and if you are using the Linux Web server you have a problem.
