There is a problem clicking to place the insertion point near wikilinks (1.9.1). Clicking to the left or right of an automatic wikilink does not place the insertion point even though the I-beam is diaplayed. Instead it always follows the link. This is particularly problematic if the wikilink is the only item in the document or if the wikilink it at the beginning of the line and you want to insert text to the left of it or the link is at the end of the line and you want to insert text at the end of the line (or end of the document if the line is also the last line in the document). The workaround of clicking in other nearby non-wikilink text and using the arrow keys to place the insertion point is not very satisfactory and isn’t always an option.
Version 1.9.2 will probably add the possibility to ignore the link and to set the insertion point instead by pressing a modifier key.
