Visual Studio 2005: Controls being moved automatically?

I have been using Visual Studio 2005 for a while now and there have been too many occassions where some of my controls just seem to "move on their own".

The controls I am talking about are buttons situated on a splitcontainer with开发者_JS百科 Anchor Top, Right. (Perhaps the anchor has something to do with it?)

How it should be:

How it was this morning when I opened my project (this has happened more than once by now), note that the buttons are no longer situated as close to the right border as in the previous picture:

This is mildly frustrating as I have no idea how to Google this, it will probably be the result of my own doings. If I have missed any information you require, please let me know.

Thanks in advance!

Anchor them propely and fix the size of the form to a minimum size so that all controls are in proper place.
