Does anyone else have a hard time using similar worlds?

it takes me forever to click on something, theres times i just didnt use it cause of that, it took me a long time just to put this question up, i did contact similar worlds about it but sometimes it still happens, its not my laptop cause if i go anywhere else it works okay, so am i the only one. ive thought of not using it at all cause its a pain to get it going so if noone sees me thats why
