Dear Mr. Buil:

I am very very sad to tell you that according to those suggestions sent in Yahoogroup, I STILL can never use 5.0.2~~
1). I select smallest characters [my PC has 3 types: small (small is the standard and normal one);big;very big].
2). in "Appearance"---"effect": I uncheck "use big symble".
3). In "Screen resolution” function from desktop, my PC has: 800x600; 1024x768; 1280x600; 1280x720; 1280x768; 1366x768. Usually I just use 1366x768, this time I select 800x600, and plus (1)+(2) setup above, but ISIS can never work and no change. I can never see the contrast slider.
Another strange thing is that I have flat images in working directory as f-1.fit; f-2.fit... f-15.fit, open f-1, click >, image name displays f-11!
In old version 4.3.0, everything works very well. i.e. I name: rho_cas3'-1.fit, here 3'= 3 minutes. Even so 4.3.0 can recognize all images.
I'd like to ask you: if you have old 4.3.0 or others backup? If at last 5.0.2 i can not use, I have to use old one. Could you send me an old version? And I'd like to suggest that you put old versions link for us to download when we want to go back...
