This should be fixed in the current version - now providing you keep the shift key down misclicking won't cancel the selection1. When clicking multiple taxi links (the lines between the dots) to make them straight, if you misclick one, you have to start again from the first link. It is quite frustrating when you have many small links to click.
To clarify, I do hold down the shift button to select multiple links, but should I misclick a link, I can continue to select multiple links. However, the option to straighten is no longer available, or if I wanted to edit them, clicking Edit does no good. Also, if I do not click the links in sequential order, I do not get the Straighten option.
If I click only the links, I get the Straighten option (and clicking Edit results in a Properties window).
If I click one link, then click something other than the link (in this case, the background), then click the second link, I no longer have the option (and clicking Edit does NOT result in a Properties window).
