This just shows a message on the map telling you to turn off internet explorer compatability mode. It is annoying but not harmful.
The only way to resolve this is to add registry keys in Windows using Regedit.
At two locations add a DWORD called iexplore.exe with a decimal content of 11000
HKLM\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
Right-click the key and select New > DWORD.
Give that DWORD the decimal value of 11000. This will make all sites render without compatibility view.
To prevent the notice coming up in a particular program add a DWORD in the same location as follows -
Zipsys - add ZIPSYS.exe with a decimal content of 11000
Loadmaster - add Loadmaster.exe with a decimal content of 11000
Sameday Express - add Same Day Express.exe with a decimal content of 11000
