My Guest frequently locks up on PSF access - oh, okay, after a couple of minutes is does usually unlock and proceed VERY slowly. I guess that is okay - unless of course if I am busy. Sometimes, it just never comes back, sometimes it is just ridiculously slow.... that is fun as well and also convenient. Guys, all I am trying to do here is unzip a file on a PSF, or edit a Word document. Nothing complicated. Version 1970, updated tools, etc.... Performance has been like this since early betas and has not gotten better. Given that 1970 was an official update release, I was honestly expecting more. Sorry for the sarcasm, I am just frustrated. I am depending on this product now for my daily work activities and I am getting a bit intolerant of the PSF stuff. Is something going to be done here to make this better, please?
