Wow! What a great plugin... 
I can not thank you enough to make this possible on sketchup... Where have I been so far to miss this wonderful plugin. SU Team surely should incorporate this in SU native version. I believe they will put this in the new Trimble Sketchup... Great work Fredo!!! and thanks once again....

Could you open the Ruby console and check if there are some errors reported there.
The situation is rather strange however.
I would suggest you try with the other tools to see if you have something similar. All tools share a large part of the selection processing code, and this would help me to better figure out where this could come from.
Hi Fredo,
At the first, I was thinking that there's something wrong with the copy I got, so I downloaded a fresh new copy and replaced the old one in the plugins directory. But the problem still remains.
As you suggest, I just checked the ruby console and found no error there. I already tried other tools as well, and the selection's just fine. Here I attach the selection using RoundCorner tool (which is another awesome work of yours). I found no problem using this tool. Is it because I am using SU7?
Thank you so much.
Best Regards...
Thank you very much for your quick reply, and forgive me for this late reply. I've just busy with the office and didn't notice if your reply was very quick.
Well, I think it's not about the model. the problem is that I can't make the model using curviloft, because I can only select one segment of a curve. I can't select the whole curve/spline...
I already watch the tutorial video on youtube. I just follow the given instructions. But, still I can't select the whole curve or the whole spline.
Here I attach the situation of my "all curves selection disability"... I hope this will give you a better view of my problem.

Thanks before. And I do apologize if I just missed a basic setting to solve this...
Fredo, I am a real newbie, as you can see, this is my first post.... I know you've produce many plugins. And those plugins are really helpful I believe. I just started to check this plugin section of the forum, and found that you're a master here. Thank you very much for bringing sketchup to a further stage as a modelling software... 
I just downloaded your curviloft plugin and already installed it on my sketchup7 pro (windows7 platform). But, I got some real problem related to selection. I tried to follow the tutorial step by step. I tried the pre-selection mode. I selected the paths (two curves, I put one above the other), then click the "face icon" button. As we know, the curve is constructed by several connected lines (segment). And as I click the "face icon", just one segment can be selected, and I've no idea how to select the whole segment of the curve (or both curves).. I got the same problem also to apply the loft between two surfaces.. I just can select one segment.. 
I can't even select the whole segment of the curve using manual selection mode... Forgive me if my problem is very basic thing... FYI, I Already tried the whole selection options... but nothing could worked it out. Do you know how to solve it? Please..., your help will be greatly appreciated..
Thanks a lot.....
