Changing tabs on ssh causing shrinking text

Hi,

I'm having an issue when I have multiple putty sessions opened in tabbed mode. When I change tabs and then go back to the previous tab, the text is squashed on the left hand side of the screen. As soon as you do something it outputs fine on the screen at full width.

I'm also having an issue when clicking on menus or right clicking, it takes multiple attempts to get the menu to stay up so i can use it.

Thanks
