Attachments problems

HelloI have two problems with attachments and inotes:

1- When we open an attachment it is saved and stored on the local drive. But I only wanted to see it, to open it.

=> Why is it saved?

=> Is it possible to change a parameter to avoid the default save on the disk?

2- Saving an attachment on the disk with inotes, the attachment has the time of the save on the disk. With lotus notes, the attachment keeps its creation/modification date.

=>Is there any solution?

thank you

regards
