The dialog box included both text and an image (bitblk). Sometimes it worked, sometimes three boms appeared when trying to open the dialog box (that happened both in the RCS and in the apllication using the resource). It turned out that the problem is the generation of the .RSC file by the RCS. First the resource header (as defined in one of the header files) is generated. Then all the strings used in menu's, TEDINFO's, alertboxes, etc. After that follow the bit images of the images and the icons. These images have to start on a word boundary |||||||||||| When the total number of bytes in all the strings (including the ending nulls) is odd you will have a problem. The remedy is simple. Construct your resource. Save it. Load it again. Try to open something with an image or icon in it. If boms occur, change one of the strings (doesn't matter which one) by adding or deleting one character (a space probably). And, magic, it works.
