Being a shell extension, TSVN *can* get loaded by IE, but only if
another IE plugin loads it. IE itself doesn't load such shell extensions.

You could check whether TSVN is loaded into IE process space using the
process explorer and searching for "tortoisesvn.dll". If it's loaded by
IE, it will show up under the IE process.

One issue that usually happens when shell extensions are loaded is that
the CWD path can get changed. TSVN therefore saves the CWD on entering
any method and restores it when exiting that method. But while executing
some methods, TSVN can change the CWD temporarily (this happens in the
svn library, so no way for TSVN to prevent that).

But tools running in IE should *never* use the CWD anyway since even the
media player plugin for IE changes the CWD (and doesn't restore it).

Apart from the CWD, I can't think of anything why/how TSVN could break
apps running in IE.
