Description
Reported by Paul Jolly; checked by Reinier Sterkenburg
You can end up in a situation were you can't view component icons that you have placed.

To reproduce the problem:

  1. Create a form or a datamodule.
  2. Place 4 table icons on the components page, lined up vertically.
  3. Select all four table icons.
  4. Click and drag all four icons by pointing at the bottom icon.
  5. Drag them up the page so that 3 tables are out of view and the fourth one is at the top of the page.
  6. Notice how the scroll bars have not changed, indicating that the first three tables are not accessable.
  7. Deselect the four tables by left clicking in white space.
  8. Tables 1,2 and 3 can no longer be viewed although the object inspector (or the tree view on the left hand side) indicates that they exist.
I think this is a bug because I expect to be able to view and arrange those table component icons.

Eddie Churchill (Inprise/Borland) commented to this (15 Dec 99):
This bug actually applies to D4, D3 and D2 as well. While there may be problems with the components view in D5 but this particular bug is alas, universal.

Solution / workaround
David Christiansen provided two workarounds (22 Dec 99):
  1. Go to the top-most visible table, press the up arrow key, then use Ctrl + Down until it scrolls back onto the form.
  2. View the module as text and manually modify the top property of the component
