How to desable reloading of the already loaded pano?

For example we have this tour: sample
When pushed the "other panos" button we see the thumbs of all panos. When we click thumb of already loaded pano, this pano is start to reload! But we don't need it. I have not straight solution of this "unnormal" for my tour behaviour. Who knows how to solve this problem?

UPD: My nonstraight solution. I linked desabling of click on thumb action to check of coordinates of plugin "ramka". This plugin is the border around thumbnail of loaded pano. I have 10 thumbs in 2 rows (5x2), and in this case I need to check two coordinates of "ramka". Coordinates of "ramka" on loaded "hall" pano (and active "hall" thumb) is x=125 and y=183

not work:

<action name="load_hall">
		ifnot(plugin[ramka].y==-183,loadpano(hall.xml,null,null,BLEND(1)),ifnot(plugin[ramka].x==125),loadpano(hall.xml,null,null,BLEND(1)));
		set(plugin[ramka].x,125);
		set(plugin[ramka].y,-183);
	</action>

not work:

<action name="load_hall">
		ifnot(plugin[ramka].y==-183,action(load_hall_yes),action(load_hall_no));
	</action>


	<action name="load_hall_yes">
		loadpano(hall.xml,null,null,BLEND(1));
		set(plugin[ramka].x,125);
		set(plugin[ramka].y,-183);
	</action>


	<action name="load_hall_no">
		ifnot(plugin[ramka].x==125),action(load_hall_yes));
	</action>

I'm not programmer, and my brain is already boiling. Where my mistakes?
