First things first......
Did you do as I suggested and scroll down to the bottom of the left paned "Search" list and deselect
"Show Search Preview page on right" button?
Does this retain your original page after typing word[s] in the search field?
I believe the blank page is produced by one of the known bugs when using the "Preview" feature of your search. Here is a list of some known causes and fixes:
If you have enabled Search Preview, but do not see the Search Preview page [in the right pane] submitting a query in the Search pane, it may be one of the following problems:
1]You have Internet Explorer 6.0 on Windows XP and are running Search Companion instead of Search Assistant. Follow the steps in How do I enable Search Preview on Windows XP to disable Search Companion and enable Search Preview.
2]You are using Search Assistant, but do not have MSN Search as your default or sole search provider. Follow the steps in How do I set MSN Search as my default or sole Search Assistant provider to set MSN Search as your primary search provider.
3]Your Internet Explorer security or privacy settings prevent Search Preview from enabling. If your Internet Explorer security is set to High you will not be able to use Search Preview. Also, if your Internet Explorer privacy is set to Block Cookies or High you will not be able to use Search Preview.
4]Search Preview has been temporarily disabled by MSN Search administration. Normal functionality should return within a few hours.

The second issue you mentioned is with the "Go To" button. This is a short list from your most recent cached "History" of pages visited. As such this is also subject to having an occasional link to a blank or a java script that loops you back to the same site.
Instead, change the way you work with search results.
Don't just click on a link; right-click and choose Open in New Window, or drag the link to another open browser window.
When you view the search hits in a separate window, you don't have to worry about getting back to the main search page.
NOTE*There are also known problems for non patched/updated IE's and blank page issues but it sounds like yours is the common known quirk we all put up with from time to time.
There are many more methods of doing a search in a more user friendly way. The above nfo is just one. My personal preference
is with the "Google" toolbar but I digress and that is another Topic best addressed in the "General Forum".
